After some effort, I believe I have a working BitBake recipe for cross-compiling fossil in an embedded Linux distribution built by the Yocto Project's BitBake tool. .... I'll post my recipe for building fossil itself separately, after I've verified that the fossil it builds actually does run in my target hardware.
I've attached the BitBake recipe that worked for me. Put the file in ~/yocto/poky/meta-myproject/recipes-myproject-extras/fossil and make sure that some other recipe as a last resort ~/yocto/build/local.conf mentions a need for "fossil". You might want to tweak the options passed to ./configure to suit.
I don't happen to care one way or the other about SSL, so I ignored it both in the ./configure and in the documented dependencies. As luck turned out, libssl was already built and present when this recipe was built and ./configure noticed it, so the fossil as built got the related features.
I've (lightly) tested the result in an image running in a very tiny Gumstix Duovero OMAP4-based system by cloning my project's repository, opening a working folder, and successfully building it in the target with GCC.
To learn more about Yocto, see https://yoctoproject.org/ for plenty of documentation.
